Abstract
A compute-in-memory circuit based on charge redistribution includes a memory array, multiple-functional output units (MFUs), multiplexers (MUXs), and a word line (WL) driver. The memory array includes memory cell rows and memory cell columns. Every two adjacent memory cells form a memory cell pair in sequence, and every two adjacent memory cell columns form a memory cell column pair in sequence. A grounded register capacitor is connected to a source line (SL) of each memory cell row. Input ends of each MFU are connected to a first bit line (BL) and a second BL of each memory cell column pair, respectively. Each MUX includes voltage-input ends and an output end, and the output end of each MUX is connected to the SL of each memory cell row in a one-to-one correspondence. An output end of the WL driver is connected to a WL of each memory cell row.
